Application filed April 5, 1918. Serial No. 228,845.

To all whom it may concern:

.Be it known that I, CHARLES B. HEIM, a citizen of the United- States,and a resident of Marco, county of Greene, and State of Indiana, have'invented a certain new and useful Tire-Vuleanizer; and I do herebydeclare that the following is a full, clear, and exactdescriptionthereof, reference being had to the accompanying drawings, in which likenumerals refer to like parts.

This invention relates to vulcanizing tools and is designed, primarilyfor applying a patch to the inner tube of automobile tires. One featureof the invention is the provision, in connection with a work holdingframe, of a clamping foot, and a cam lever for operating the clampingfoot for raisin and lowering the same. A further eature of the inventionis the provision of a pin or roller on the shaft on the clamping footfor cooperation with the flange of the cam portion of the lever forraising and lowering the clamping foot and holding the same in loweredor elevated position. i

A further feature of the invention is the provision of means forremovabl securing the clamping lever to the frameo the device toposition the same directly over the upper end of the shaft and theclamping A further feature of the invention is the provision of meansfor adjusting the clampmg foot with respect to the shaft carrying thesame...

The full nature of the invention will be understood from theaccompanying drawings and the following description and claims Figure 1isfa side elevation of the vuldevice showing same in operation in fullnes and the position of the lever in inoperative position by dottedlines. Fig. 2

is a sectional view as seen on line 22 of Fig. 1, and Fig. 3 is anelevation of a sli htly modified form of device.

eferring to the drawings in which similar' reference numerals designatecorrearts throughout the several views, 1 in icates a frame which issubstantially U-shaped, one arm thereof having a base 2, while theopposite or upper arm is provided with a socket 3,-said socket beingpositioned above and in line with the axial center of the base 2.Slidably mounted through the socket 3 is a shaft 4, to the lower end ofwhich is adjustably secured a clamping foot 5, said foot being designedto engage the peripheral flange 6 of a fuel cup 7, and direct downwardressure thereon when desired. The clamping foot 5 is secured to the endof the shaft 4 by extending a screw 8 upwardly through the axial centerof the lclam ping foot and into a threaded recess or socket 9 in thelower end of the shaft 4 and in order to increase or decrease the len 8is made of su cient length that washers I 10 may be introduced aroundthe screw between the end of the shaft and the clamping foot. In thismanner it will be seen that the greater the number of washers placedbetween the end of the shaft and clamping foot, the greater the lengthof the shaft, thereby obtaining a greater degree of pressure upon theshaft and clamping foot.

Extending upwardly from the frame 1 is a bracket 11, to which ispivotally attached a lever 12, said lever having a cammed head 13through which extends a ivot pin 14, said pivot pin being threadhd intothe h of the shaft, the screw bracket 11, so that the lever can bequickly removed or attached. Extendin laterally around the edge of thecammed ead 13 is a flange 15which is eccentric to the ivot pin 14, theouter face of said flange eing esigned to travel. over and engage theupper end of the shaft 4 to direct downward ressure thereon when thelever is in its owered or operative position.

In order to raise the shaft 4 and the clamping foot attached theretothrough the medium of the lever 12, the upper end of the shaft 4 isprovided with an angular extension 16, the vertical arm 17 of which projects above the inner face of the flange 15 and carries a pin or roller18, said roller projecting over the flange so that when the lever isthrown upwardly to the position shown by dotted lines in Fig.1, theshaft 4 and clamping foot 5 will be elevated, the curvature of theflange being such as to hold the shaft and clamping foot in elevatedposition when the lever is thrown upwardly its full distance. I

The flange 15 is also so curved that when the lever is thrown downwardlyor to the position shown in full lines in Fig. 1, the clamping foot willbe pressed tightly against the' fuel cup 7 and the material tightly impinged between'the cup and the base 2, the.

flange 15 locking the clamping foot and I a. screw extending throughsaid foot; and

shaft in clamped position. Y cy In Fig. 3 of the drawing a modified form5' of the device is shown, and i 1 this-instance the upper end of theshaft 4 is pivotally attached to a walking beam firucture ld thefl i-extending through an elongated slo -l21 'inlthe'j end of the walkingbeam 19, so as to permit swing.-

pivot pin 20 for the s ing movement of the b eamQ g The walking beam ispivoted at its center to a standard 22 Whichprojects upwardly from theupper arm of the frame 1, the op-, posite endof the walking beam fromthe" end attached to the shaft 4 having a lever- 12' pivotally attachedthereto,;said lever having a cam-med head 13 which cooperates withtheframe 1 for rocking the walking the clamping foot 5" from the'fuel'cup" 7",

I the weight of said lever will hold the clamp-' ing foot in itselevated position, In this device' washers 10 are also' provided forlengthening or shorteningthe-shaft 4?, the

- remaining parts of the modified-form or device being the. same asshown in the pre tofsaid bracket, a laterallyuextending flan e I on saidlever adapted to extend over and rent pressure on said shaft, saidflange being "ferred form. e
